%X The algorithm based on mathematical morphology was presented in order to decrease the influence of background to mutual information registration measure.The noisy background was replaced with single intensity background through binariza- tion,morphology processing and background replace.The local extremum of single background was decreased,and the regis- tration measure was improved.
